Hey guys !
My first thread here. Been reading here since vanilla, so im glad that i finally can bring some to the table. Im unsure if its an exploit/guide or just part of the game.
I recently discovered that the power pylon, and conduit pylon(all the pylons, but the others arent interesting), can be used when fighting bosses/uber bosses.
Just start the boss-timer, and meet up by a conduit-pylon before last party-member clicks accept. This requires that you are in party with at least one friend.
